Remove Unnecessary Confirmation Popups -- resolved, but why not effective?
They were removed, but then some were added back later.
Some are still removed, such as copy and paste for objects.

However it seems the confirmation popups for delete and save have been re-added after a bug report, and for good reason IMO. I hit those keys accidentally rather often, and I try to avoid reflexively undoing as much as possible due to various limitations (not to mention speed).
